Be itiknown-.that I, BERNARD LOEWE, a citizen of Turkey, residing atfZurich, in the 'Gantoniof' Zurich, Republic ofSwitzerland, have innented certaininew and uscitullmprovements in `,Spinning and 'Piecing Appa1.'atus,lot which-thefollowing is a vspecification. 1-

This invention relates to .spinning machines with a p'iurallityifof spinningfdevices comprising each a spinning tube formed with spinning eyes, and one or more discs rotatable around the axis of said tube.

According to this invention on this disc and eccentrically to the axis of said spinning eyes, one or more filament guides are provided by which the spun filament is polished and evened, and if desired, also receives a twist. Further the improved apparatus also allows of doubling one or more laments to form a. thread. According to the position of the nature or" the filament guide the filament may be twisted or not and `polished more or less thoroughly.

Two constructional forms of the improved apparatus of this invention are illustrated by way of example in the accompanying drawing in which:

Figures 1 and 2 are respectively a vertical sect-ion and a plan (from below) of a filament piecing device with a filament guiding eye adjustably mounted with varying eccentricity on the revolving disc.

Figure 3 is a section through -a filament piecing device having two revolving discs of which the upper one contains a filament guide.

The spinning and piecing apparatus illustrated in Figures 1 and 2 consists essentially of a tube 1 with a piecing disc 2 situated beneath it formed with marginal notches 3. This tube and disc are rotatable in a casing 4 provided at the top with a screw-in tubular cover 5 which carries a fixed tube 6 (piecingtube) extending into the spinning tube 1. The usual fixed eyes 7 and 8 made of agate, glass or other suitable material are mounted on the cover 5 or spinning tube 6.

The actuation of the tube 1 with piecing Vdisc 2 is effected by means of an endless driving belt 9 which is pressed against a disc 10, mounted on the tube 1, by means of a disc 11. l

Below the notched disc 2 there is mounted as a filament guide, an eye 13 carried by fanarim i111 piveted :at .By. slriftingf the r.arm-14:, the.` eye 13 can .beinoved belowptlre notcln 16, nearerl to or iaway; from; -the, center of the disc 2. The angle made by the Isilk filament i 17 .in passing from the zeyelet 13 :to the, 4,eye 7 can i therefore be adjusted as .desired v In itspassage through theeye v7 theaffilament--isrubbed so that it is, polished and all its .irregularitiesarerevened; F01' .the Apurpose of ffacilitating lthe ,threading of the filament through the eye 13, the latter may be brought to the center of the disc. By making this eye 13 suihciently narrow so that it is capable of taking up the filament during the rotational motion of the disc 2, a certain amount of twist can be given to the filament. By providing two eccentric eyes 13 below the disc'2, two silk filaments can be twisted together.

The apparatus illustrated in Figure 3 comprises two revolving discs 20 and 21. The lower disc 21 is notched in a similar manner as the disc 2 of the first example and serves for the piecing of the filaments (silk filaments of cocoons for instance). The upper disc 2O carries an eccentric filament guide 18 in the form of aL ring or`- traveller adapted to be brought in different positions with regard to the axis of the spinning eyes. In this spinning and piecing device the cocoon filaments pieced by the disc 21 are twisted by the disc y2O as they pass out of the eye 8', thus promoting the adhering together of the separate cocoon filaments which are to be united to form one compound filament. A further result is a better polishing action in consequence of the inclined position of the filament between the eye 8 and the filament guide 1S and also in consequence of the twist given to the filament. This twist is lost again on the spools of the winding apparatus, but however it has helped'in uniting and polishing the filaments. The funnel-shaped cavity formed by the disc 2O may be utilized for containing solutions of an adhesive or the like, for treating the filament in its passage between the eye 7 and 8 or between the eye 8 and the filament guide 18. The spinning tube 6 is held within the piecing tube 1 for instance by means of screws 25.

used also for doubling the filaments issuing from the tube 6, two conical discs are em-` ployed, one on each end of said tube and each provided with an eccentric thread guide and a driving disc.

What I claim is:

1. In a spinning machine, spinning devices comprising each a spinning tube provided With spinning eyes, at least one disc capable of rotating about the axis of said tube, a filament guide mounted on said disc in an eccentric manner relatively to the axis of said spinning eyes so as to polish and even the filaments during their passing through said guide and the neXt spinning eye.

2. In a spinning machine, spinning devices each of which have a spinning tube provided with a spinning eye on each end, a disc capable of rotating about the axis of said tube, a filament guide mounted on said disc in such a manner that the amount of its eccentricity in relation to the fixed spinning eyes can be varied,

3. In a spinning machine, spinning and piecing devices comprising each a tube provided Wit-h a fixed spinning eye on each piecing end, a disc loosely mounted on this tube and adapted to rotate about it, the cavity of the disc containing a solution of an adhesive through which the filament is moved, a filament guide mounted on said disc in an eccentric manner relatively to the spinning eyes of the piecing tube In testimony whereof I-have aixed my signature in presence of two Witnesses.
